This is awesome. The car by itself is already extremely well formed and very convincing, and then on top of that it also transforms into a decent enough robot. For the robot mode, I particularly like how the back of the torso looks. The rest is a bit too chunky for my personal taste, however that means that G1 Transformer fans will love it. Great work, and I hope to see more!
I am always amazed at how people are able to do this, I have several Transformer concepts I've been working on, but my mind just can't handle all those moving interlocking parts. Great looking as both car and robot, though I think the car is the better of the two. Nice work.
